To all whom 'it ymay conce/m:

Be it known that `I, PHiLo V. SNow, a citizen of the United States, and a resident ol' Chicago, county of L-ook, and State of Illinois, have niadc and invented certain new and useful lniproveinents in Photol Metal, of which the following is a spcciication.

'lights of the picture and giving greater My invention relates to the production of prints on metal and has particularly t do with both the process involved inl the production of the prints and with the com` pleted article.

The object of my invention is to provide a photograph, wash drawing, or other pic. torial representation, on metal, so produced as to present a highly artistic and pleasing appearance, having nidividuality, radiance and color, as well-as depth, tone and luster,

fai' superior, so far as I am aware, to any p print heretofore produced.

A furthe-r object of my inventionis to produce a print onmetal wherein the picture will'stand out in a vivid and realistic manner, will contain to a surprising degree, warmth, depth and Color, and also will present a highly artistic and radiant appeal'- ancc, due to the presence of local portions possessing increased light 'reflecting or diffusing value,`thus intensifying the high lus-` ter and contrast.

A further'object is t0 provide a method for producing' prints possessing; the above characteristics. and which process may be readilycarried ont with uniform etlicient resuits.

One feature of my invention is disclosed in the accompanying drawing, which forms a part ol this specification.y

ln making a print containing' the characteristic features of `my invention and produced under iny new process, a negative is lirst inade froni a photograph. This negative may he oliilaincd from a carriera, or may luin' the nature of a hall' tone, or ,possess any other desired i-liaractcristir. A ini-tallic siirl' ciis then prepared for the reception. :if :i sensitixinir solution and to this end l preferably employ a sheet of inetal siiclras coppia:v brass` sili'cr.y gold plate, ctc., which iiiillii iiliilv is reinen.; slziii' spots, grain. or Qther blemish, and. is :wel: a polish. The polished nietalthoroughly cleaned so as to lic surface is then evenly coated with 'a sensitizingsolution in theusual manner, the sensitizingsolution being of such quality as to withstand rubbing and properly receive a dye. The picture is then printed from the negative Idirectly' on the sensitized metal sheetr The print havingbeen thus inade and developed, it is next dyed with a suitable dye of the desired color, as, for example, with an anilin dye, the color of the dye being chosen so asto both harmonise with the subject-matter of the picture and with the color of the metal sheet.

The surface of the print is then rubbed so as to produce an even tone or shade and reinov any stains or strealis which may be left by the dye, this step l preferably carried out while the print still wet.

The print is then dried, iiicn is eferably accomplished by laying a cliaaxncis skin on the'inetal print and strueegceing the same, although this drying may be carried out 1n other ways, as will be readily appreciated. i a

After the print has been thus dyed., rubbed and dried, it is more ci' dull and flamand in order to it depth, radiance and luster, it is then polished.l which Vl`have found may be expeditiously carried out by using a mixture of substantially four parte of powdered charcoal and one part of puin ice stone, which mixture is applied in a dry state to the print and rrdihed down wil'i a piece of cotton batting' until the desired smoothness, luster and rel tive effect is had. It will here be readily apja'eciated that this polishing may be carried ont in other inanners Without departing .from tl e, spirit oi: my invention The polishing of( the print may be carried to thcI extent of either pal'- tially or completely rcnionngi local portions ot" the print or local pm'tions of the hall" tone d0ts,vso that an increased light retlection will take lare from these local por tions of the 'polishml metal surface. thereby intensifying tl'. h lights of the print and adding' Inatci nity to its individulftlity,

specificati/on of Reissned Letters Patent. 119155119@ luay l()a 192L pletely free from the picture or half tone lines'or dots. Thus the area B will either partiallv or completelv expose thepolished metal plate C and an increased light reilection will takeplace at this area or portion,

lthe result being an intensification of the higlr lights and a marked increase the contract and luster of the print. ,i

The print is then cleaned and given'a final polish "which may be effectively carried out by a clean sheet of chamois, after 'which the print is coated witha'suitable preservative so as to prevent oxidation or` deterioration.v I have found that a suitable lacquer. which is either sprayed on or applied by dipping, forms a ,very desirable i preservative coating.

After the printhas been completed it niav be framed or mounted on a'suitable backing'rtlanrl the warmth and color of the metallic sheet, combining and blending as it does with the dve, and the two being augmented by the brilliancy of thevhigh lights,
